What causes two distinct pressure zones between the equator and the poles?

a. the troposphere interacts with the stratosphere
b. gravity
c. the coriolis effect
d. ionospheric interactions with radiation

The best and most correct answer among the choices provided by the question is the third choice "the Coriolis efffect"

The Coriolis effect is most apparent in the path of an object moving longitudinally. On the Earth an object that moves along a north-south path, or longitudinal line, will undergo apparent deflection to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

I hope my answer has come to your help. God bless and have a nice day ahead!
